This invention relates to closuresfor dis- Y lcharge valves' for retortsand more particu- 'larly' forA the closure of' the bottomloiV vert1- YcalE orinclined ret-orte intended forthe distill ation oi soil'idl c'arbonaceous substances.l

, Ehe inventionA has amongits objectsitfo 'provide-a perfectly gas tig-ht closure involv-e ying4 thel use et'V a door-which can be readily operable fiar'V opening orclosuraandf which does not require the use of any ,bol-ts or other devices, that needl unfasteningl or fasl tenmg'en thekopeningor closure; A The invention comprises the construct-1on- 'l'ustrated intleaecompanying drawings in Figure l represents ai sectionalV elevation A of a. closure or, discharge vaive'rfor retorts Vac@Ording tortheA` ln'vention i lustrated in the accompanying drawings,a vdoor a in the form of a cylindrical sectorv such as hereinbefore described is mounted partiallyv to rotate upc-nits axis within-a semi-cylindrical casing b having its cylindri- @al wall b3 provided with opposit'ely disposed e 30 flanges 1 by meansroi` which the parallel disposed lateral walls '6? may be secured to the cylindrical wall b? by. suchl Vmeans, as

rivets. Vlhe casing ZJ Ais. thus open' at .its f lowerend which is mounted and secured within a dish-shaped receptacle 0 within which a liquid such as water is maintained above the'level ofthe loweredge of the respective cylindrical andglateral walls of the It will thus be understood that the casing '7) may be made of plate or sheet lmetal' asl mayfalso the door 'a and the.dish-shapedre-A ceptaclec, but no limitation made to the utilization of plate or sheet metal.

The door a maybe formed of a sheet bent.

in the form of af sector having a cylindrical wall a and two oppositely disposed and parallel walls a2 and a radial wall a3 the respec 'tive walls being integrallyvformed or se#` cured together, .and the door so formed may be carried upon arms ai whichY may be integrally formed or mounted upon the axleve, which is Vcarried inv suitable bearings or stuiing boxes in therespective longitudinal Walls c1 of the dish-shaped vreceptacle a One end of theax'le e may be-provided of a' square section for the neceptionfoff` a wheel'-iff or handle by means offwlnch thev doorm-ay 1 it from the closed position indicated: inf-full lines in Figure linto the open positinn` in# dicated 1n dotted lines in. that figure;h where-5i by the retort /fr beneatlr Awhich thecasing; b

Thus it will Vbe understood that the dish! shaped receptacle has at one side of the axle e a tubular part 02 extending upwardly within the casing-b in alignmentwith the v'tubular part or fitting b4, andthat 'aspace is left between the upper edge of theV tubular 1 part o2 and the cylindricalwall b3 as Well las between the tubular parte'2 and the oppositely disposed lateral walls b2 of the casing*y i 5,' so as rthus to accommodate the cylindrical l wall al and the oppositely disposed vlateral walls a2 of thedoor a on its being' rotated intoy its closed',position'.V It-will furthermore be. understoodthat inasmuch as the lower edges of the cylindricalwa'll ail-andthe lateralV fwalls [a2v of the door vare disposed *in line, these will pass into the' liquid or water seal ofk the dish-shaped receptacle o, on the# door assuming the closed position indicated in .Figure1,v and inasmuch as the lower edges `of the cylindricalk l l Wall b3 and of the lateral walls bzfof the casing vb' also extend .into theliquid or waterY seal within the dish-shaped receptacle, thel f lower end of the retort is closedy with agas tight seal on the door being moved into itsclosed'position7 while on the door being rotated into its open position a, clear passage is nevertheless provided Y through `which the charge may pass frornthe retort through the tubular partsoi ittings b4 and 02.

I i VThe easing?) inay be iixedly secured in the Y position indicated inrFigure l by any suitvable means .whereby the lower edge ot the for said opening comprising in combination ya door inthe forni ot ay cylindrical sector, a
